Some people on GLP-1 meds notice changes in their mouth. Dry mouth. Sensitive teeth. Sore gums.
It's not the medication attacking your teeth directly. It's usually the side effects doing it.
What People Notice
- Dry mouth – Less saliva than usual
- Tooth sensitivity – Hot and cold bother you more
- Gum changes – Bleeding or soreness
- Bad breath – From dry mouth or nausea
Why This Happens
Dry Mouth
GLP-1 meds can reduce how much saliva you make. Saliva protects your teeth. Less saliva means:
- More cavities
- Sore mouth
- Bad breath
- Changes in taste
Nausea and Vomiting
If you throw up often, stomach acid hits your teeth. That acid wears down enamel. Thinner enamel means more sensitivity.
Dehydration
GLP-1 meds can dry you out. Less water in your body means less saliva. It's a chain reaction.
How to Protect Your Teeth
- Drink water – Sip throughout the day
- Brush twice a day – Use fluoride toothpaste
- Floss daily – Don't skip it
- Chew sugar-free gum – Helps make more saliva
- Rinse after vomiting – Wait 30 minutes, then rinse with water. Don't brush right away — it can damage softened enamel.
- See your dentist – Regular checkups catch problems early
- Tell your dentist – Let them know you're on a GLP-1 med
When to Call the Dentist
- Tooth sensitivity that won't go away
- Bleeding or swollen gums
- Dry mouth that doesn't get better
- Mouth sores that don't heal
- Any sudden change in your mouth
The Bottom Line
GLP-1 meds don't directly hurt your teeth. But side effects like dry mouth and nausea can. Stay hydrated, keep up with dental care, and tell your dentist about your medication.
